  • Patent number: 10323747
    Abstract: A piston ring that is pre-treated by grit blasting to a defined roughness, followed by PVD coating with a metal nitride to a thickness of at least 10 ?m, leaving peaks and valleys in the coated piston ring. The coated piston ring is then lapped to remove the peaks without penetrating the coating, so that valleys and plateaus remain in the coated surface. The resulting piston ring exhibits superior coating retention due to the increased surface area created by the grit blasting, and yet also superior performance, as the cavities remaining increase the porosity of the coating and thus enhance the lubrication of the ring.

  • Patent number: 9814519
    Abstract: A tissue ablation probe comprises an electrically conductive probe shaft, at least one electrode, and an electrically insulative sheath disposed on the probe shaft. The insulative sheath has thickened regions forming alternating ribs and depressions that longitudinally extend along the probe shaft. The ribs allow the ablation probe to be delivered through a tightly toleranced delivery device. While the ribs may shear off during the delivery process, the underlying probe shaft will remain covered by the remaining portion of the insulative sheath. The tissue ablation probe may be used in a tissue ablation assembly that additionally comprises a delivery cannula having a lumen in which the tissue ablation probe may be removably disposed. In this case, the sheath has an outer periphery having a size substantially the same as the diameter of the lumen, so that the inner surface of the delivery cannula cooperates with the depressions to create lumens that longitudinally extend within the cannula.

  • Patent number: 9795439
    Abstract: A bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from its distal end. Each jaw member is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of selectively conducting energy through tissue held therebetween. A knife channel is configured to reciprocate a cutting mechanism therealong. An actuator selectively advances the cutting mechanism. A switch is disposed on the first shaft and is configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a mechanical interface disposed on the second shaft. The first position of the switch relays information to the user corresponding to a desired pressure on tissue and the at least one subsequent position is configured to activate the source of electrosurgical energy to supply electrosurgical energy to the jaw members.

  • Patent number: 9743984
    Abstract: Devices and methods for delivering fluid to tissue during ablation therapy are described herein. An exemplary device can include an elongate body having an inner lumen, outlet ports, and an ablation element configured to heat tissue. A flow resistance of the elongate body can increase along a length of the elongate body containing the outlet ports in a proximal to distal direction. This can be accomplished by, for example, varying outlet port size or relative spacing, decreasing a cross-sectional area of the inner lumen through which fluid can flow using a flow diverter or tapered inner lumen sidewalls, or limiting a ratio between a total area of the outlet ports and a cross-sectional area of the inner lumen. Adjusting flow resistance of the elongate body can provide more uniform fluid distribution or a desired non-uniform distribution.

  • Patent number: 9717558
    Abstract: An ablation electrode is mounted on the distal end of a catheter with a first portion inside and a second portion outside the catheter. The second portion is adapted to have a surface that makes maximum contact with a tissue to be ablated, leaving a minimum area not covered by the tissue and potentially exposed to blood. The first portion is adapted to provide an extended surface area for efficient exchange of heat with a coolant flowing inside the catheter. Outlets provided near the area not covered by the tissue in the second portion prevents blood from getting close to or come directly in contact with the area, thereby greatly reducing formation of dangerous blood clots. The minimizing of an electrical circuit through blood greatly reduces wasted power into the electrode so that the efficiently cooled electrode is not burdened. The catheter preferably has multiple electrodes with similar features.

  • Patent number: 9681915
    Abstract: Medical methods and devices for treating aortic dissections. A catheter-based cutting device permits cutting a septum of acute or chronic aortic dissections, in a retrograde manner. The catheter includes a base section having a central lumen therethrough, two flexible arms extending from a distal end thereof, where each arm has a channel therethrough for a passage of a guide wire. With distal ends of the two flexible arms separated, the two arms form a Y-shape with the base section. With distal ends of the two flexible arms together, the two arms have a longitudinal profile, about a periphery thereof, identical to a longitudinal profile of the base section. A non-mechanically actuated cutting component resides between the two arms in a vicinity of the distal end of the base section. The cutting component faces distally outward between the two arms with the distal ends of the two flexible arms separated.

An end effector assembly is disposed at the distal end of the shaft and includes first and second jaw members. One (or both) of the jaw members is moveable relative to the other between an open position and a closed position for grasping tissue therebetween. Each of the jaw members defines an opposed jaw surface and is independently coupled to one of the first and second shaft portions. The first and second shaft portions are configured to flex relative to one another during movement of the jaw members to the closed position to grasp tissue therebetween such that the opposed jaw surfaces of the jaw members are disposed in substantially parallel orientation relative to one another when grasping tissue therebetween.

  • Patent number: 9655638
    Abstract: The patent is relative to a new instrument for single access laparoscopy that tries to overcome the limits of the present instrumentation used in this technique, that usually allows to use only one forceps, which does not allow to keep the tissues tenses to work with the surgical instrument. To overcome this limitation, the proposed instrument presents two arms, arranged in parallel presenting a diameter equal to half of the main body in the opening direction of the same, while in the direction perpendicular to this these arms can have an higher diameter, provided its shape be entirely circumscribed by the external dimension of the initial body, and each bearing at the tip a forceps, which may be mounted directly on the arms or on two auxiliary arms. The internal mechanism allows opening the two arms, not necessarily in the plane of rotation of the control rings, while the forceps bend toward the inside, keeping their configuration, being all this controlled by a single command.

  • Patent number: 9615876
    Abstract: A device for morcellating tissue within a body cavity of a patient comprises a stationary tube (8) having a distal end portion, and a bipolar electrosurgical electrode assembly (13) located at the distal end of the tube. The electrosurgical electrode assembly (13) comprises first and second electrodes (14, 16) separated by an insulation member (15). When an electrosurgical cutting voltage is applied to the electrode assembly (13), and relative movement is initiated between the tube (8) and the tissue, a slug of resected tissue is formed within the tube such that it can be removed from the body cavity of the patient. The bipolar electrosurgical assembly (13) has a first circumferential region (A) and a second circumferential region (B), the first circumferential region (A) being longer than the second circumferential region (B), the bipolar electrosurgical assembly being adapted to cut tissue preferentially in the first circumferential region (A) as compared with the second circumferential region (B).
